Tuesday primary not make or break for Santorum

Although he finished last in Saturday’s Nevada caucuses, former Pennsylvania Sen. Rick Santorum said Sunday he’s not quitting the race for the Republican presidential nomination anytime soon.

Asked on “Fox News Sunday” whether this Tuesday's three-state voting is a “make or break” moment for him, Santorum replied: “Oh no. Not at all. I think we’re going to show improvement. This race is a long, long way from being over."

Santorum has maintained that he’s the only conservative candidate to front-runner Mitt Romney who could beat President Barack Obama in a general election match up. And he predicted he’ll have a better showing during Tuesday in Minnesota, Colorado and Missouri.

“We’ve got three states coming up on Tuesday,” he said. “We’re going to show that this race is moving in a very different direction.”
